I see a handling problem ofering links to the user before he / she has *saved*
the preferenced. The links about skin ".css", ".js" user page and user talk page
should apear *after* saving the preferences / creating an account but probably
not after log in.

I've reverted r38587, r38589 for now in r38610.
This clutters up the prefs UI with a lot of links which don't currently apply, most of which will never be used. It also isn't clear how it would apply to proposed non-skin-specific pages such as User:X/common.css/.js and User:X/print.css
